TIN-CLEANING DEVICE.

Specification of Letters Patent.

Patented Feb. 18, 1919.

Application filed. August 14, 1918. Serial No. 249,871.

To all whom it may concern:

Be it known that I, Una U. IlLAM, a citizen of the United States, residing at Chester, in the county of Hancock and State of West Virginia, have invented new and useful Improvements in Tin-Cleaning Devices;

specification.

My present invention pertains to tin cleaning machines; and it has for its ob ject to provide sheet separating means for use in conjunction with such machines, the said means being adapted to effectually prevents sheets of tin from cobbling in a cleaning machine when two or more sheets are fed simultaneously to the machine.

The invention in all of its details will be fully understood from the following description and claims when the same are read in connection with the drawings accompanying and forming part of this specification, in which:

Figure 1 is a front elevation illustratlng the sheet separating means constituting the best practical embodiment of my invention that I have as yet devised.

Fig. 2 is a transverse section taken in the plane indicated by the line 2-2 of Fig. 1 looking toward the left.

Fig. 3 is a front elevation of a modification of my invention.

Fig. 4 is a transverse section taken in the plane indicated by the line 1-4 of Fig. 3 and showing the manner in which sheets of tin are separated incidental to the passing of the same through a cleaning mechanism.

Similar numerals of reference designate corresponding parts in Figs. 1 and 2 to which reference will first be had.

My novel organized mechanism for separating the tin sheets includes among other elements an upper shaft 1 and a lower shaft 2. In the preferred arrangement the lower shaft is provided with a sprocket gear 3 for connection with suitable power means, and the two shafts are connected together through the medium of the intermeshed spur gears 4:. My mechanism also comprises spaced wheels 5 arranged in vertical alinement and suitably fixed to their respective shafts, and disks 6 arranged in vertical alinement and loosely mounted on their respective shafts, and maintained in spaced relation between the wheels A, through the medium of sleeve sections 7 or other suitable means. The said disks 6 are slightly smaller in diameter than the wheels 5 so as not to give rise to friction. Being fast on their respective shafts the wheels 5 are utilized to convey the sheets into the front end of the cleaning machine.

The disks 6 are equipped with laterally disposed blades 8 which extend beyond their perimeters and are adapted to separate or maintain the sheets of tin in spaced relation while the sheets are passing through the cleaner. In order that said blades 8 may be properly adjusted to fit different sizes of tin sheets I prefer to adjustably connect the blades to the disks 6 by providing the blades with shanks 9,longitudinally slotted at 10, and arranged alongside the disks 6 and connected thereto through the medium of bolts 11 which extend transversely through the disks and are equipped with nuts 12. Manifestly this construction may be depended upon to prevent casual move ment of the blades relative to the disks, and yet when desired change of position of the blades may be readily accomplished. As many of the blades 8 may be employed on the disks as required and as many disks may be used as is deemed necessary, and when two or more sheets are to be separated the blades 8 may be set at difierent lengths on different disks-2'. a, may be made to extend a greater or less extent beyond the perimeter of the disks. I would also have it understood at this point that the blades 8 of the disks are adapted to be used at opposite sides of the disks as shown in Fig. 1; also that the faces of the disks may be of any desired width or widths.

In the embodiment shown in Fig. 3 the loose disks 6 and 6 are held against casual lateral movement on their respective shafts by adjustably fixed collars 15, and the upper disks 6 alone are equipped with blades 8; the said blades in the preferred practice of the invention being disposed at opposite sides of and carried by each disk 6*. The lower plain disk 6 have their peripheral portions opposed to the disks 6 and arranged in vertical alinement to said disks 6*, and consequently the said lower disks 6 serve to hold the sheets up to assure accurate operation of the blades 8. At this point it will be noticed by reference to Fig. 4: that the back blade 8 must touch the sheet at the same time the front blade touches the sheet that it engages. For this reason the adjustable capacity of the blades is important. It will also be noticed that the adaptability of the lower disks to hold the sheet upwardly in position precludes the possi bllity of upward bounce and the objectionable consequence of two sheets passing under a blade.

Having described my invention what I claim and desire to secure by Letters-Patent is:

1. In sheet separating means, the combination of lower and upper feed wheels opposed to each other, lower and upper loosely rotatable disks opposed to each other, and blades carried by one of said disks and extending beyond the perimeter thereof.

2. Sheet separating means for use in conjunction with sheet feeding means, comprising lower and upper disks one of which is provided with blades that extend beyond its perimeter.

3. Sheet separating means for use in conjunction with sheet feeding means, comprising lower and upper loosely mounted and opposed disks, and blades carried by Copies of this patent may be obtained for five .cents each, by addressing the. Commissioner of.Patents, 1

and extending beyond the perimeter of one disk and adjustably fixed to and adjustable radially on said disk.

4-. In sheet feeding and separating means the combination of lower and upper shafts, intermeshed gears connecting said shafts,

opposed feed wheels fixed to the shafts, op-

posed disks loosely mounted upon the shafts, radially adjustable blades carried by one of the disks and extending beyond the per. imeter thereof, and means on the shafts for maintaining the disks in spaced relation to the feed wheels.

In means for the the combination with a disk,-of a radially adjustable blade disposed at one side of the disk and adapted to extend beyond the imeter thereof and having a longitudinally slotted shank, and connecting means between the blade and disk extending through the slot in the shank.

In testimony whereof I- aflix my signature.
